All ATK Up Book Locations in Castlevania: Belmont's Curse

Once you have the Arcane Whip, go to the lower part of the Sewer Reservoir and use the anchor to come up from below.

Can be found in the Old Gallery of the Main Hall. Head to the right of the room, use the Portrait Anchor, and shoot yourself up at the eastern end of the room.

Located on a small ledge in the northwest corner. Head to the east side of the room and use the anchoring point above the exit to bounce off the wall allowing you to latch onto the anchoring point above the spikes to the west.

Continue west, avoiding the spikes by jumping over them and using the anchoring points to end up on the ledge with the upgrade.

Can be found in the Counterweight Chamber of the Clock Tower. Hit the Lever past the blocks and then race back to the entrance of this room to get the Upgrade before time runs out.

Coming from the west, use the lever to lower the drawbridge, moving the anchor point higher. Use the anchor point to get on the drawbridge that just lowered and head into the combat challenge room. Defeat the enemies and drop into the room below to get the upgrade.

To reach this ATK Up Upgrade, you need to enter the Tomb of the Chevaliers via the hidden entrance to the east.

From there, use the anchor to reach the collapsing platforms above the spike and jump across them without using Aerial Rush and then wait for the laser to fade before using the next anchor.

Use Aerial Rush to the right from here and latch on to the final anchor to get the upgrade.

To reach this ATK Up upgrade in The Tomb of the Chevaliers in Notre-Dame, head toward the northwest exit and you’ll find a gap you can slide under to reach a hidden area.

Here, while timing with the lasers, drop down, use Aerial Dash to reach the far wall and wall jump off it to make your way up to the upgrade.

Can be found in the Tree of Saints of Notre-Dame, sitting to the right of the tree itself.

Located in the Overgrow Crypt in the Holy Innocents’ Cemetery. Go through the hidden area east of this and go through the door it leads to.

To reach the ATK Up in the Narthex of Notre-Dame, you first need to obtain Double Jump.

Once you have that, leap up to the platform on the left and use the anchors to reach the top of the room.

Jump across to the east using Aerial Rush and break the wall, then drop down to the platform.

Located at the end of the hidden path accessed by sliding under the gap to the east.
